Who are the Process Players (BPM/Workflow)?

Rather than assume we know it all when it comes to the world of Business Process Management (BPM) and Workflow, we're looking for feedback (as we did with Findability) on what companies should be considered on the list of solution providers for BPM and Workflow.

The twist is that we are not limiting this list to "pure-play" BPM providers, as fun as that might be.

We're interested in Document-centric Workflow/BPM and Transaction-based Workflow/BPM as well, which heads into the direction of larger platforms - Enterprise Content Management (ECM) suites as well as Enterprise Resource Planning (ERP) suites. (If you care about business process - does it matter to YOU whether it's baked in to a bigger solution, or prefer BPM that is agnostic?)

Below is a guaranteed incomplete list of the types of providers we're considering having listed in the upcoming BPM survey. Who are we missing, and for that matter, who shouldn't be on the list? Even given acquisition/consolidation, it's a big ol' world of process.

The proposed list:
Adobe
Alfresco
Autonomy/Cardiff
BEA
Corticon
DST
EMC/Documentum
Flowcentric
Fuego
Fujitsu Interstage BPM
Handysoft
IBM/FileNet
IDS Scheer
Intalio
Integrify
K2
Legato
Lombardi Software
MetaStorm
Microsoft
Open Text
Oracle
Pegasystems
Progress Software (Sonic/IONA)
SAP NetWeaver BPM
Savvion
Singularity
Skelta
Software AG
SpringCM
TIBCO
Ultimus

So, who are we missing, and for that matter, who shouldn't be on the list? For example, does Adobe belong on this list? If no, why not? If yes, why? or Oracle? In or out? SaaS and Open Source options - SpringCM and Alfresco. Valid? Useless? (for this list)

Anyone representing a solution provider who should be on here, feel free to weigh in, don't be shy - there's no magic involved in this list. Process practitioners/consultants, your insights are especially wanted.
